Increased Use of Open Redirects in Phishing Campaigns
Kroll’s Cyber Threat Intelligence (CTI) team has been tracking an uptick in phishing campaigns utilizing open redirects. Open redirects are vulnerabilities commonly found on websites that allow for the manipulation of legitimate URLs, which actors can leverage to redirect users to arbitrary external URLs. They occur when a website allows for user-supplied input as part of a URL parameter in a redirect link, without proper validation or sanitization.
